.mp4 pages download the .mp4 file instead of playing the file within the browser.
Firefox used to just play the videos within the browser but recently it stopped. It also stopped playing videos on streamable.com. I have media.wmf.enabled and media.play-stand-alone set to true.

Try : uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files and C:\Program Files(x86) Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :
